Picocoraciae

Picocoraciae is a clade that contains the order Bucerotiformes (hornbills and hoopoes) and the clade Picodynastornithes (containing birds like kingfishers and rollers, and woodpeckers and toucans) supported by various genetic analysis^{[1][2][3][4][5][6]} and morphological studies.^[7] While these studies supported a sister grouping of Coraciiformes and Piciformes, a large scale, sparse supermatrix has suggested alternative sister relationship between Bucerotiformes and Piciformes instead.^[8] This group was defined in the PhyloCode by George Sangster and colleagues in 2022 as "the least inclusive crown clade containing Buceros rhinoceros, Coracias garrulus, and Picus viridis".^[9]
